Teledyne Relays has introduced the Series GA152 family of highly repeatable, ultraminiature broadband attenuator relays for attenuating RF signals in 50? and 75? systems over a frequency range from DC to 5 GHz. The GA152 relays offer a normally- closed low-loss, bypass path and an attenuation path....

The Series 24 Serial Control Switch Relay (SCSR) and Serial Lock-Out Relay (SLOR) from Electroswitch facilitate remote control, monitoring or lock-out of circuit breakers while retaining local control through a manual trip/close handle. Addressable network devices, the SCSR and SLOR combine the functions of multiple devices, and they provide remote trip-coil monitoring, sequence-of-events reporting, system battery monitoring and self-diagno...

Targeting test and measurement equipment, Panasonic Electric Works' SON (Small Outline No-lead) Series of PhotoMOS relays come in a 2.95 x 2.20 x 1.40 mm package. The ceramic-constructed components come with gold-plated leads, side solder fillets and a MSL 2 rating. The product line-up consists of the CxR5 C-type with a load voltage of 25 V, and the CxR10 C- and R-type with a load voltage of 40 V....

Measuring 0.62? × 0.43? × 0.44?, Hasco Components International's SPDT relay switches have a current of 5 A with a less expensive 2 A option. The device exhibits a coil voltage range from 3 to 48 V DC with a sensitive version for drawing less current. The relay offers a maximum switching voltage of 60 V DC or 120 V AC, and switching power of DC 30 W or AC 60 VA....

Teledyne Relays introduces a new series of DPDT surface mount ultraminiature relays that deliver RF performance over a bandwidth from DC to 8 GHz. Signal integrity of the GRF312 performs up to 12 Gb/s. The relays are designed to provide a practical surface-mount solution with improved RF signal repeatability over the frequency range....

While model-based design is becoming quite standard for several domains that have similar constraints as wireless sensor networks, there is a lack of tools for this purpose in the WSN world. By Stefano Olivieri, The MathWorks, co-authored by Mostafizur Mozumdar, Luciano Lavagno and Laura Vanzago.
Wireless Sensor Networks (WSN) have become a hot research topic and show much promise to become a driver of current and future microelectron...

Virtual System Prototypes (VSPs) offer a means to develop and debug embedded software before the silicon is available. By Jeff Roane, VaST Systems Technology Corp. As the semiconductor industry continues to consolidate off-the-shelf hardware components to build wireless consumer devices, such as 3G phones, these devices are increasingly differentiated by software content....

Emulating the way that the human hearing system characterizes and groups the audio stream into sound sources proves to be an extremely efficient and accurate way to suppress both stationary and non-stationary noise. By Lloyd Watts, Founder and CTO, Audience
